Abstract
The invention relates to an ultrasonic sensor arrangement (2) for a motor vehicle (1), comprising a trim element (3), in particular a bumper, comprising a radiator grill (4), and at least one first and one second ultrasonic sensor (5, 6) each comprising a membrane (11) for emitting and/or receiving ultrasonic signals, wherein the first ultrasonic sensor (5) with its membrane (11) is arranged on a back side of the trim element (3) so that the membrane (11) of the first ultrasonic sensor (5) is configured for emitting and/or receiving ultrasonic sensor signals through the trim element (3) and the second ultrasonic sensor (6) is arranged on the radiator grill (4). By detuning means (7, 9) the second ultrasonic sensor (6) is detuned and hereby its emission and/or receiving behavior adapted to the emission and/or receiving behavior of the first ultrasonic sensor (5).
